Compare and contrast the various organs and their order through the body. What role does each of them play (function, physical or chemical action?)
Which organisms have similar organs in the digestive system? How does that compare to the types of food that they eat?
How is the organ adapted to provide as many reactions as possible in the shortest amount of space?
How are the same design features found in the parts of the cell as well as in other organisms and the environment?
1. Compare and contrast the various organs and their order through the body. What role does each of them play (function, physical or chemical action?)
pig: the oral cavity, the esophagus leads to the stomach, small intestine, and large intestine. Other organs develop during fetal pig development such as the gallbladder, pancreas and spleen are all critical in contributing to the overall flow of the digestive system. After being digested and absorbed, the food follows through the large intestine. Crayfish: the order of the crayfish organs are eye, green gland, mouth, mandible, esophagus, maxilliped, ventral nerve cord, ganglion of central nerve cord, digestive gland, flexor muscle, anus, extensor, muscles, gonad, heart, stomach, and encephalon. Starfish: The mouth of a starfish is located on the underside of the body, and opens through a short esophagus into firstly a cardiac stomach, and then, a second, pyloric stomach. Each arm also contains two pyloric caeca, long hollow tubes branching outwards from the pyloric stomach. Each pyloric caecum is lined by a series of digestive glands, which secrete digestive enzymes and absorb nutrients from the food. A short intestine runs from the upper surface of the pyloric stomach to open at an anus in the center of the upper body. The similarities of these organs are that they all have something that performs the most basic tasks that need to happen for them to live. They are different because some have organs that others do not have. They also have different organs that perform different tasks. 2. Which organisms have similar organs in the digestive system? How does that compare to the types of food that they eat?
A human has a similar organs to humans because they are similar in functions and size, this could be because they eat many fruits that we eat also.
The crayfish has a similar digestive system to the grasshopper because they have three main parts, which is the foregut, the midgut and the hindgut. This is probably because they eat small insects. The starfish has similar digestive enzymes to humans, fetal pigs and mussels because they are used to break down food particles. This is probably because it’s a simple organism so there are not many complex organs inside it. 3. How is the organ adapted to provide as many reactions as possible in the shortest amount of space?
All of these organisms organs are adapted to provide as many reactions as possible in the shortest amount of space so that it is the most efficient animal, and so it can stay alive in the environment that it is in. 4. How are the same design features found in the parts of the cell as well as in other organisms and the environment?
The design features found in parts of the cells as well as in other organisms and the environment would be similar because they would need around the same things to cause similar reactions because they live in the same area and would most likely eat around the same things.
